In Mr.Martinez's sixth period class, there are 8 boys and 12 girls. what is the probability of randomly selecting a girl?

To make the trinomial a perfect square, we can complete the square. The value of c that makes the trinomial a perfect square is c = 25/4.

To make the trinomial a perfect square, we need to find the value of c. We can do this by completing the square. The trinomial can be written as x² + 5x + c = (x + a)², where a is a constant. Expanding the right side, we get x² + 2ax + a² which is equal to x² + 5x + c. Comparing the coefficients of x, we have 2a = 5. Solving for a, we get a = 5/2. Substituting this value back into the expression, we have x² + 5x + (5/2)² = (x + 5/2)². Therefore, the value of c that makes the trinomial a perfect square is c = (5/2)² or c = 25/4.

Answer:

23.08 %

Step-by-step explanation:

Markup price is the difference between the selling price and cost price of an item.

m = Markup = 30

s = Selling price = 130

[tex]\text{Markup percent on selling price}=\frac{m}{s}\times 100\\\Rightarrow \text{Markup percent on selling price}=\frac{30}{130}\times 100\\\Rightarrow \text{Markup percent on selling price}=23.08\ %[/tex]

∴ Markup percent on selling price is 23.08 %

Answer: B

His slope should be positive because the trend line is slanted up to the right.

Step-by-step explanation:

from left to right the line is increasing upward so it is positive so this means both of the bottom answers are wrong. answer A. is wrong because even slopes that are negative have all points positive sometimes so this is not a valid reason. therefore this leaves us with the answer B, which is correct.

His slope should be positive because the trend line is slanted up to the right. which is the correct answer would be an option (B).

The variables in the scatter plot made from the data are described by the independent variable, time, which is graphed along the horizontal axis.

Jordan is calculating the slope of the trend line in the given scatterplot.

As per the given scatter plot, the required solution would be as:

Take two points (1,24) and (8,96)

So, slope = (96-24)/(8-1) = 72/7 = 10.28

The line is moving upward from left to right, hence it is positive, implying that both of the bottom solutions are incorrect. Answer A. is incorrect since even negative slopes can have all points positive at times, hence this is not a legitimate argument.

As a result, we are left with solution B, which is accurate.

Answer:

mean trust me

Step-by-step explanation:

247.52 centimeters.

To find this answer, you have to find 91% of Robert Wadlow's height. To do that, you multiply 272 by 0.91, which gives you the height of Zeng Jinlian.

Answer: D. Mildred is correct because she distributed 5 correctly.

Step-by-step explanation:

Since, the loss of water in one day = [tex]2\frac{1}{4}\text{ inches}[/tex]

⇒ The loss of water in 5 days = [tex]5(2\frac{1}{4})\text{ inches}[/tex]

⇒ The loss can be written with negative sign,

Thus, the expression that shows the changes in quantity of water in 5 days,

[tex]-5(2\frac{1}{4})[/tex]

[tex]=-5(2+\frac{1}{4})[/tex]

[tex]=5(-2-\frac{1}{4})[/tex]

[tex]=-10-\frac{5}{4}[/tex]

[tex]=-10-1\frac{1}{4}[/tex]

[tex]=-10-1-\frac{1}{4}[/tex]

[tex]=-11-\frac{1}{4}[/tex]

[tex]=-11\frac{1}{4}[/tex]

Since, the above steps are similar to that of Mildred's solution,

⇒ Mildred is correct.

Also, By the above explanation it is clear that jermaine incorrectly distribute 5 in his third steps.

⇒ Option D is correct.

In a direct variation equation, the graph passes through the origin (0,0). Every point on the graph can be represented as (kx, ky), where k is a constant.

In a direct variation equation, the graph passes through the origin (0,0). This means that when x=0, y=0. Every point on the graph can be represented as (kx, ky), where k is a constant. For example, if the direct variation equation is y = 2x, the graph would pass through (0,0), (1,2), (2,4), (3,6), and so on.

To find the square footage of a wall painted blue, you would first calculate the total size of the wall by multiplying the wall's height and length. Then, you would multiply this number by the proportion of the wall you plan to paint blue. This will give you the number of square feet that will be coloured blue.

This question pertains to the mathematical concept of resolving problems involving areas and percentages. Marcus's wall's total area can be calculated by multiplying the wall's length and height. However, since the measurements have not been provided in the question, let's assume their values to be 'L' and 'H' feet respectively. The area of the wall would then be simply H*L square feet.

Now, if Marcus decides to cover a certain percentage of this wall with blue paint, we must determine the total square feet being painted. If the proportion of the wall to be painted is 'P', the blue-painted area is given by H*L*P (P being a decimal representation of the given percent, i.e., 20% would be represented as 0.20).

Therefore, the number of square feet that will be blue is the product of the total wall area and the proportion to be painted blue.
